traction resistance meaning in Chinese

牵引阻力

And the primary and secondary relation of the factors and the optimum level of every factor were obtained as well as the best scheme of structure design in the research condition . regression equal between traction resistance and partial sphere height , bottom circle radium was set up to explore the effect of two evident factors ( height and bottom circle radium of the partial sphere ) on traction resistance by optimum calculation
采用二次回归试验设计的方法，建立了球冠高度和球冠底圆半径大小与牵引阻力间的回归方程，进行了优化计算，进一步考察了球冠高度和球冠底圆半径大小两个显著性因素对牵引阻力的影响规律。
